[Serusers] newbie to SIP Express Router

Hi, I am newbie to ser, and wnat to install and configure ser on my computer. Still I am reading infomration on internet for the configuration and installation of ser, but any information provided on this forum would certainly help me a lot. Here are the details. My OS RedHat linux 9. i have downloaded ser-0.8.11-0.i386.rpm and installed it simply by command rpm -i ser-0.8.11-0.i386.rpm what to do next? Why i need ser? Actually i have to show working ip-telephony service as a requirement in our course. The scenario is that, we have our private LAN (intranet) and i have to install and configure the ip-telephony service so that one cleint on the intranet can call other client on the sane intranet, i will use either Kphone or BonePhone as a client. So if some one can help me in establishing this service. I dont need to call outside my intranet or even i dont need some advanced features like security/authentication or any other thing other thing. -ajeet. stockholm. -- Ajeet ajeetnk(a)fastmail.fm -- http://www.fastmail.fm - IMAP accessible web-mail
